Can not upgrade to B390 (C432) - Huawei P9 Questions & Answers

Hi,
I'm on C432, unlock bootloader. (It's a debranded phone).
I can't update. to B390.
I did a clean install of B386 using TWRP (flash the 2 zip file, clean cache). B386 works fine.
Update from phone did upload the B390 update, it rebooted into Huawei recovery and it failed at 12%. "Software installed failed".
So I've tried with TWRP (I have downloaded the B390 from Firmware finder) and it fails on update.zip with an error 7.
I've tried various versions of B390 (from Firmware finder) and they all fail when trying to install update.zip from TWRP.
Flashing back B386 with TWRP works (no errors when flashing update.zip).
It seems the update.zip from B390 tries to look for something missing in my phone....
Any ideas ?
Thanks !

Stay on B386 unless you're really keen for the latest security update.
Peace.

I can' t even go back to B182, B383. Only B386 I can install (hopefully). This tells me that something is corrupted in my phone.
I have the following error with TWRP:
assert_failed: block_image_verify("/dev/block/platform/hi_mci.0/by-name/system", "package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat")
ERROR 7
With other update.zip, I also have
assert(update_huawei_pkg_from_ota_zip("UPDATE.APP"));
What's wrong in my phone ?

albelushi7 the problem is that update.zip fails with TWRP because of the assert.
I guess the problem is because my VENDOR, PRODUCT, VERSION are probably corrupted (or may be other partitions).
I can't flash them using fastboot.
I looking for a TWRP backup of these partitions for a L09C432 model. Can someone share a backup of these partitions ?
(Even a full backup with B390 installed for a L09C432 would be great !)
Thanks !

I'm going crazy with this. Tried to rollback to MM everything time I try to flash, it fails.
Either by
- TWRP : Update.zip fails with ERROR 7
- Huawei updater + HiSuite
- 3 Button methold and dload folder.
I can only flash B386. It works fairly OK but with some random crashes.
I don't understand what's wrong with my phone. It was an Orange phone, debranded to C432. I had several updates without any issues and problem came since B383.
Could not update with Phone updater to B386. Did with TWRP. But now, I can't install anything. Only B386 can be installed !!!

same thing happen with my phone. now, i use c185 with b390. you should try the same.

So you flashed the OemCust for C185 and it worked ? Good to know !
You were on C432 before ?
Did you try revert back to your original OemCust ?
Thanks !

Hi! I had the same problem. I solved it in this way:
Backup app+data with titanium
Revert to MM with the official procedure, upgrade via updater to nougat and install, always via updater the updtes until B390. Works everything.
The I reunlocked bootlader via adb, install twrp, rooted and restore apps with titanium.
Long procedure, but it worked

How lucky ! I did install MM Rollback and then MM (C432B136). I was on stock recovery and bootloader locked.
Update B136 -> B160 : Ok
Update B160 -> B182 : Failed
Now I can barely install anything (B386 anymore, it used, now it doesn't). Only TWRP...

When I downgraded to MM I was already on b182. I immediately had the nougat update available.

Fixed my bricked P9 on B166 how do i update to the latest Nougat build??

I previously attempted to get on to the latest Nougat FW which ended up in a soft brick which required DC-Phoenix to fix after flashing a b136 recovery rom back to the phone. I have unlocked bootload, but dont think i have root or TWRP installed anymore, im guessing after a complete recovery stock rom flash that gets removed, is there a way to check?.
What is the safest method for me to get to MM B166 FW to the latest Nougat FW please?
EDIT: am now on B182 updated via HiSuite

Even eRecovery fails to install a PV version

Hi,
My P9 has a weird problem. I can't install any official firmwares : They all fail when installing, whatever the method : 3 buttons, HiSuite + Proxy, Firmware Finder + Proxy on phone, even eRecovery with DNS change.
It's a L09C432 (debranded, used to take updates fine before B383).
Using eRecovery, I'm trying to install as many firmwares as I can, hoping one will install. So far, I've B360-FullOTA-MF-PV, B386-FullOTA-MF-PV without luck.
Is there a "clean-up" package somewhere ?
Any suggestions ?
Thanks !
Install the official firmware over TWRP Recovery. It should also install the stock recovery, so the next time when you reboot into recovery it should be the stock recovery.

Can't update from .106 to .107 (CLT-L29 C432) - tells me zips are corrupt

Hi all,
I am on a P20 Pro EU Version (CLT-L29 C432) with firmware 106.
What I wanted to do is update from 106 to 107. I have:
- unlocked bootloader
- TWRP installed (tried with official and Pretoriano80 version {https://forum.xda-developers.com/huawei-p20-pro/development/recovery-twrp-3-2-1-0-t3779400})
- Huawei Firmware Finder
- Patched bootloader from here as well back when the only possibility to install magisk was via patched bootloader (self-created from 106 boot img)
What happened so far is:
1) got the official update notification -> small OTA install failed -> received full update -> failed
2) tried install via TWRP with downloaded OTA from https://forum.xda-developers.com/hu...rmware-release-clt-l29-8-1-0-107c432-t3779167 -> tells me zip is corrupt (=failed)
3) install via twrp and select update.zip in Huawei Firmware Finder folder -> zip corrupt -> failed
4) installed via dload method - tried small and large update file --> "Software install failed"
so yeah. i dont really know where to go from here and the google maps issue is really bugging me, so i def want to update
appreciate any help
OTA fails = you have TWRP installed
TWRP installation fails = TWRP cannot install these OTA files (what I know of)
Install orig recovery and use the FF proxy method.
thanks @fregor - do you by any chance know where I could download it? I could only find firmware files
use the initial method download the ota unzip it put it in folder named dload and proceed to the update by turning on ur phone while pressing both volume keys
just tried with the 500mb ota and get a "software install failed"
will try with the big one if i somehow find the DL location of it
alright man, I have downloaded the full update via FF. when i unzip the "update.zip" i always get a file is corrupted error. happens on mac and on windows :/
AND downloaded it from here http://pro-teammt.ru/firmware-database/?firmware_model=CLT-L29C432&firmware_page=0 --> software install failed again
kinda lost now tbh
thank you all for your assistance - what helped in the end was using zxz0o0's tool HuRUpdater. It flashes FULL official firmwares without the online check. Can be found here: https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
